    Every Wilwood brake rotor is cast from premium grade, long grain carbon iron. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.

    These scalloped iron brake rotors provide effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges. Steel rotors are typically found in lighter weight open wheel cars such as sprints and modifieds.  Speedway's premium 11.75" x .810" drilled scalloped brake rotor weighs only 5.07 lbs.

    • Scallop configuration provides greatest weight reduction on a vented straight vane iron rotor
    • Scallop machining removes as much as three pounds, or nearly 33% of the rotor mass
    • Vented castings provide increased cooling capacity over machined steel plate rotors
    • Improved structural durability over drilled rotor designs
    • Vented iron 
    • Inboard mounted (Sprints)

    Note: Suitable for Light Dirt Racing applications. Scalloped Rotors are unsafe for street use.

    This cast iron RH slotted pillar vane rotor from AFCO is designed to give superior strength, decrease rotor weight, and run cooler. Each pillar is diamond shaped and precisely positioned to optimize pad surface support thereby eliminating rotor cupping.

    • Manufactured with premium grade alloys to thermal shock stability
    • Double disked ground to ensure precise flatness
    • Slotted to eliminate brake grassing to reduce pad tapper and increase contact between rotor and pad
    • Rotationally balanced to reduce vibration and improve traction

    When it comes to brake rotors, racers are constantly searching for the ultimate balance between the lowest weight and the ability to effectively manage heat. Decreased rotating weight in the drive line provides quicker deceleration under braking and quicker acceleration out of the corners. Lower weight also benefits handling with improved spring and shock control over the unsprung suspension mass. Wilwood's ULD-32 drilled iron rotors provides effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges.

    • Cast from premium grade, long grain carbon iron
    • Close tolerances on face and vane thickness
    • 32 straight vane casting provides superior heat management and long service life
    • Two row, 64 hole pattern - alternates between and directly over each vane
    • Each hole deeply chamfered to eliminate stress points
    • Rotating and unsprung rotor mass reduced by 12%
    • Left or right hand mounting locations

    Wilwood's Drilled Steel brake rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. Steel rotors are typically found in lighter weight open wheel cars such as sprints and modifieds. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads.

                Wilwood's 3 hole mount rotors are precision CNC machined from high strength billet plate. Full symmetrical machining provides perfect balance, perfect flatness and the truest rotation of any rotor being built. These rotors fit the popular 3 x 5.00" mount bolt circle found on most sprint and midget front hubs. Wilwoods engineered drill slot pattern combines the highest degree of weight reduction with the highest resistance to thermal distortion in the contact faces. You get smooth engagement and a consistent full pedal from the low knock-back characteristics of this design. A durable black anodized finish prevents corrosion and simplifies the visual inspection of the contact faces. The best results are always achieved using PolyMatrix Q compound brake pads with these rotors.
    • Unsafe for street use & unsuitable for most forms of Racing.
    • Special racing application only. IE. Dirt Sprint & Midget.
    • Can result in catastrophic failure when misused.
